Run safe, high-yield codebase maintenance passes that trim dead code, vestiges, duplicate implementations, stale scripts/configs, and excessive LOC without churn. Use when the agent is asked for a maintenance pass, cleanup pass, code cleanup, slop trimming, dead-code removal, de-duplication, vestige pruning, or refactors whose purpose is reducing maintenance burden rather than adding features.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Maintenance Pass ## Optimize For Maintenance Yield Prioritize the safest change with the largest maintenance payoff. Delete or simplify code only when evidence supports it. Refactor only when it materially reduces duplication, clarifies ownership, removes a failed path, or protects an important contract. Do not move code around for aesthetics. Use this rough ranking: ```text maintenance yield = impact * confidence * stale_touch_signal / blast_radius ``` Treat time since last git touch as a triage signal, not proof. The relevant metric is the most recent commit that changed a path, not when the file was created. Code whose latest git touch was a long time ago is more likely to be a vestige, duplicated old path, or stale interface, but stable core infrastructure can also be old and correct. ## Start With Evidence 1. Read local repo instructions first: `AGENTS.md`, `CLAUDE.md`, `README.md`, nearby runbooks, and provenance notes tied to the target area. 2. Check the worktree: `git status --short --untracked-files=all`. Never revert unrelated user changes. Avoid destructive cleanup in a dirty worktree unless the user explicitly scopes it. 3. Establish stable baselines: …

How to install
mdr add uchicago-dsi/ai-sci-skills/maintenance-pass@sha256:283fd73840814534The line at the top of this page pins the label git:20260921.9b3de7c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
